| 摘 要： | 基于Lynett和Liu的水平二维内孤立波传播模型,对内波的极性转变过程进行了序列SAR成像仿真研究。通过分析下降型内孤立波转变为上升型的序列SAR仿真图像,验证了内波极性转变时在SAR图像上出现信号减弱和特征消失的现象。对比于实地星载SAR图像,仿真结果也验证了内波在传播过程中受地形变化影响而出现的传播方向平行于等深线、分裂等现象。

| Abstract: | Based on Lynett and Liu's horizontal fully two-dimensional internal solitary wave propagation model,this paper studies on series of SAR imaging of the internal wave polarity conversion process.After analyzing the simulated images during the depression internal waves converting to elevation ones,the conclusion that the radar signature of internal waves will be seriously weakened or disappeared during the polarity conversion was validated.Through comparing with the local ERS\|2 satellite image this simulation also validates the effects of ocean topography on the propagation of internal waves such as fission and isobaths\|parallelized propagation direction. |
